We got a 3 lb lobster once in Maine several years ago. Had to use a big damn knife to get into that guy. Definitely nowhere near 20lbs but damn I can't even imagine trying that guy, I'm glad they let him go.

cedarpark:FWIT, lobster's don't die of old age. They keep growing until they get eaten.

At that size I think this is its spiel to any predator thinking about a go: "Seeing that this a 20-pound lobster and could cut your head clean off, there's just one question you should be asking yourself. 'Do I feel lucky?'"
